Physics 9-26-18 Relative Motion Revisited – Motion Down a River and Kid on a Slide with a Water Gun

PHYSICS – Wow, we finally made it to the official end of chapter 3! Do you realize how much you’ve accomplished? Awesome!

How’d you do with relative motion “revisited”? You know, you’ve done this already. The only new part is the motion of objects in the same direction and opposite directions, relative to each other. Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems.

Here’s another look at relative motion – and a heads up on the kid on a slide with a water gun problem.

Need extra help? Help session tomorrow morning, Thursday, 7:20ish. UPDATE – test rescheduled for Monday!

Chemistry 9-26-18 Making Excel & Google Sheets Graphs AND Graphing Exercise 1 – 2

CHEMISTRY: Today you are going to learn (or review) how to make graphs on Excel (or other data analysis software) by watching the video below at your own pace.

Here are the instructions for Wednesday. (You are going to be dreaming about graphs before it’s all over!)

IMPORTANT: Don’t let the assignment confuse you! What it basically means is that you will make two graphs – one hand drawn and one Excel. And then, you will answer some questions about the graphs and turn in the whole assignment as a PDF – it must be submitted by this coming Tuesday, October 2, 8:00 A.M.

You can do this assignment at school or at home with your own computer. If you use any device other than a PC or any graphing tool other than Excel or Google Sheets, you may need to modify the instructions to fit your device.

  1. Under the worksheet tab, open these three graphing handouts – note, there is no handout for Google Sheets:
  2. Watch one of the vodcasts below for a tutorial on how to make graphs in Excel or Google Sheets.
    • My advice is to use a split screen view on the laptop with the video on one side and Excel open on the other side of your laptop screen. Watch the video and at the same time pause it as you follow along with the steps in Excel. Holler if you need me to show you how to do a split screen view. Or Google it! πŸ™‚
  3. When you begin working on the Graphing Exercise 1 assignment, pay very close attention to the instructions. Also, pay close attention to the sheet on How to Construct a Line Graph, and How to Make a Best Fit (Scatter Plot) Line Graph in Excel 2010 – UPDATED to make sure you have all the parts of the graph covered.
  4. Google Sheets only: If you ever need to add subscript or superscripts to the axis labels in Google sheets, try copying and pasting whatever number you need from this set in to the axis title in Google sheets: β°ΒΉΒ²Β³β΄β΅βΆβ·βΈβΉβ‚€β‚β‚‚β‚ƒβ‚„β‚…β‚†β‚‡β‚ˆβ‚‰
  5. Now go forth and conquer graphs!!

Chemistry 9-25-18 A Look at Hand Drawn Graphs

CHEMISTRY: Were you happy with your hand drawn graph? Here’s the very short review today of good and some not so good graphs.

HOMEWORK INFO: For tonight (Tuesday), make your final copy of your hand drawn graph – you’ll bring your physical copy of the graph tomorrow.

Speaking of the first graph – be careful with your hand drawn graph! Watch this vodcast for good and bad examples. Carefully review the instructions on how to draw them. Common mistakes – switching independent and dependent variables, the scale on an axis not consistent along the axis, graph too small, line not a best fit, forgetting to label the axis, etc.

And finally – NEATNESS is very important!!

Hon Chemistry 9-25-18 Physical & Chemical Changes and Conservation of Mass

HON CHEMISTRY: More review today on chemical properties and chemical changes. Can you determine if a chemical change has occurred? And what about energy? How is that important in chemical changes? Let’s play with a chemical change tomorrow!

Physics 9-24-18 Angular Projectile Motion

PHYSICS – So we are finally putting it all together – angular projectile motion! Here’s the lesson – some homework discussion and then angular projectile motion.

The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!

Hon Chemistry 9-4-18 Intro to Chemistry

HON CHEMISTRY: So now that you know how to use all the tools we’ll need in chemistry, it’s time to start talking about ….chemistry!!

Were you able to able to make applications with the branches of chemistry and categories of scientific work? We’ll finish talking about the properties of matter tomorrow. Don’t forget the applications!

Now it gets interesting! πŸ™‚

Physics 9-21-18 Horizontal Projectile Motion

PHYSICS: Great job today – and applying stuff from the last chapter no less!

Just go slow and easy, talk yourself through what you are doing and ask if the formulas you are using are legit. You’ll master it in no time flat. Watch out for squirrels throwing nuts!
